Didn't watch your link but a few months after I moved down here I caught a few Common Carp and was given a Gar and was told how to clean the gar,the fried carp was ok but no wiper.

When I was a kid we hunted every big game season in CO along with Every Species CO had to offer. With that came lots of experimental recipes & some how Canned Carp got made and if you didn't know it was Carp you'd think it was salmon.
